图5 过饱和基体中单个He泡的演变

Fig.5 Evolution of a single bubble in the supersaturated matrix (The color bar implies the values of He concentration (c_g) and vancay concentration (c_v), the same in Fig.6; Δx^*—dimexsionless length scale)
(a-c) He concentration fields under t^* = 0 (a), t^* = 10 (b), and t^* = 80 (c) (t^*—dimensionless time) (d-f) vacancy concentration fields under t^* = 0 (d), t^* = 10 (e), and t^* = 80 (f) (g-i) profiles of He and vacancy concentrations across the He bubble under t^* = 0 (g), t^* = 10 (h), and t^* = 80 (i)
